What's the use case here that isn't solved by configuring your browser to prohibit third-party cookies? Obviously browser fingerprinting and all of that can be used to try to extract the information, so browser should be strengthening their anti-fingerprinting measures. But it strikes me that this is almost entirely a client-side problem. If a server wants to give me a cookie or put something in local storage, or serve me URLs with a tracking parameter in the url, so be it -- there's no privacy violation unless they can ask another website if they know who I am, and blocking third party cookies stops that.
